Subprocessors & Platform Providers

Updated August 12, 2026

CalendarGuardian uses service providers only as reasonably necessary to provide and operate the service. Calendar platforms that a user expressly connects may also process calendar information under their own terms and privacy practices; depending on the circumstances, those platforms may act as independent providers rather than DealDoctor subprocessors.

The current core detection engine does not require a third-party generative-AI model provider. If DealDoctor adds another service provider that processes calendar content or Personal Data on DealDoctor's behalf, this page and the Privacy Policy will be updated as appropriate.
